tmeteorj recently is interested in a game Plants VS Zombies like following picture.

And his brain hole is opened so he want to you to solve this problem.
Your role is zombies' manager, and your task is place enough zombies to eat all plants on each line.
The rules are as follows:
1.Each zombies has health point from 1 to infinity.
2.Each plants has its attack point which we will tell you and will not greater than 1000.
3.All plants are so afraid of zombies, so if a plant's attack point is not greater than it's line's zombie's HP, this plant will be scared silly. So its attack point will become zero.
4.Zombies eat plants from right to the left.
5.You can place any number of zombies on each line.
Your task is to calculate the minimal total zombies' HP you need to place in order to eat all plants.

INPUT

First line, there will a number T(T≤10), means the test case of this problem.
After this, there will be a number n(n≤100), means there are n lines in the yard.
Each line contains several plants' attack points. The plants' number will not greater than 100.
There may be some blanks in anywhere.

OUTPUT

For each case, print the minimal HP for the question.

Sample Input

1 2 3 4 5
2 3 4 5

1 2 3 4 5
2
1 2 3 4 5 6

/*
遇见过的最坑的题目，主要坑点在与输入会在各处出现空格
听说还可能出现一行1500空格....
所以得用好getchar，这是关键
